JOHN H. IRVIN, OF CARLINVILLE, ILLINOIS.

CATTLE-PUMP.

Specification of Letters Patent No. 22,653, dated January 18, 1859*.

To ,all `whom it may concern.:

Be it known that I, JOHN H. IRWIN, of

Carlinville, in the vcounty of Macoupin and n responding parts in thetwo figures.

This invention relates to an improvement in water pumping devices inwhich stock are made to raise the water they drink by means of their ownweight or gravity.

The invention consists in attaching jointed or rising and fallingplatforms by means of ropes or chains to a drum which has a Ipulley ofcomparatively large diameter placed loosely on it, and connected withthe drum, when the latter is t-urned in one direction only, the drumhaving a weight attached to it, the pulley being connected wit-h a pump,and the whole arranged to operate as hereinafter shown and described soas to effect the desired object.

To enable those skilled in t-he art to fully understand and construct myinvention I will proceed to describe it.

A, represents a suitable framing in which two plat-forms B, B, areplaced, the outer ends of said platforms being connected by joints orhinges a, a, to the frame so that the inner ends may rise and fall. Thetwo platforms are of equal width and nearly equal in width to the spacebetween the sides of the framing, sufficient room being allowed toinsure a free movement of the platforms.

To the inner ends of both platforms B, B, ropes or chains b, areattached. The upper ends of these chains are attached to a drum C, whichhas two different diameters c, (Z, the chains being attached to thesmaller portion c, of the drum. To the larger portion d, o-f the drum C,a ratchet D, is attached. This ratchet is secured to the end of thelarger part d, of the drum C, and it adjoins a pulley D, ofcomparatively large diameter, which pulley is placed loosely on thedrum, or on its axis or shaft. This pulley has a pawl e, attached to it,said pawl catching into the teeth of the ratchet D, and causing thepulley to be rot-ated with the drum when the latter is turned in `onedirection as indicated by arrow l. To the larger .portion d, of the drumC, a rope or chain E, is attached. This chain has a weight F, at itslower end.

The framing A, may be sunk about two feet into the ground and theplatforms B, B, be about one foot above the surface so that theplatforms will have a rise and fall of three feet. The pulley D, may besixv feet in diameter. I do not confine myself to any particulardimensions but perhaps the above will be generally used.

Then the weight F, is down to its fullest extent the platforms B, B',are elevated to their eXtreme height, the weight F, being veryconsiderably heavier than is necessary for this purpose alone.

The pulley D, is connected by a belt with t-he wheel or shaft of a chainpump, or it may be connected with any form of pump by any suitablemeans.

The device above described is placed at the entrance of an inclosure G,within which are the pump and well. The cattle in order to get into thisinclosure must necessarily pass over the platforms B, B, and in `sodoing the platforms are depressed and the weights F, raised, inconsequence of the chains b, rotating the drum C, the pulley D,remaining static-nary. The chain E, of the weight F, is of course woundon the larger portion CZ, of t-he drum in a reverse direction to thechains b. As an animal passes off the platform into the inclosure theweight F, rotates the drum C, in the direction of arrow l, and thepulley D, will consequently be rotated with it, by means of the pawl e,and ratchet D, and the pump actuated, the weight at the same timeraising the platforms B, B', to their original position so that asucceeding animal in entering the inclosure will in its turn actuate thepump in like manner. It will be seen that the animals actuate the pumpin passing both in and out of the inclosure and a trough therefore mayalways be kept full of water for their use.

By this invention a durable self pumping device is obtained. It isperfectly immaterial as regards the weight of the animals, they cannotinjure the device as the pump is operated by a constant power, viz, theweight F, the animals merely raising the weight and not acting by theirgravity directly on the pump. The device therefore is not liable to getout of repair which might otherwise be the case in consequence of thevarying weight of cattle or in their passing over the platforms at animmoderate speed.

I am aware that rising and falling platforms have been employed andconnected with pumps in such a way that animals in passing over themwould actuate the pump, but I am not aware of any arrangement like theone herein described whereby the animals do not directly actuate thepumps but only raise a weight which serves as a constant power toactuatethe pump. I do not claim therefore the use Vof rising and fallingplatforms separately considered; but,

I do claim as new and desire to secure by 2o Letters Patent,

The platforms B, B', weight F, drum C, and pulley D, placed loosely ondrum C, and connected with it by the pawl e, and ratchet D, the wholebeing combined and 25 arranged to operate as and for the purpose setforth.
